First light for this little 50mm f1.4, set to f5.6, and my first real foray into widefield really. Three hours total (5x1800s + 3x600s). AZEQ6 mount, guided with an Altair 60mm. Really impressed with how this turned out; the limitation is the camera resolution for a change, rather than the optics /seeing etc. The exposure at f5.6 was actually accidental - I thought I was fully open at the time ! I wrapped a small heater strip around the lens, and found I could focus no problem by twisting the ring through the heater. Capture and focus in Nebulosity. Of course, now I want some OIII, but tonight's probably not the best chance - with the moon an' all. Good chance to test the lens fully open in Ha though. I've not processed this beyond a stretch, so you can see what is really happening. Tim
I imagine loads of people are collecting data from this target at the moment, with it being so high all night. This is my first go at it, and was faffing around for the first bit of the night, so only got 3x30 Ha and Oiii subs to work with, but after a lot of tweaking of colours to get it how I envisaged, here it is. The subs were guided here, but only so I could dither them. I took a 20 minute unguided sub first, just to see how well the mount tracked and it was absolutely 'bob on'. I know pointing a baby Q at 450mm isn't the biggest challenge for a mount, but with only 4 alignment stars loaded into the GM1000, I was pretty impressed with how it tracked. At first I thought there were some elongated stars, but there are quite a few in the field here which merge into each other. I've dimmed the stars here anyway to concentrate on the nebula. Hope you like it. I'm now an official 10 Micron fan. Jack
Well, it has been so long since I posted anything........I just had to. Rushed capture, severe lack of processing skill (why is every time like the first time? - try to learn again what you thought you'd grasped when you last did this 3 months ago....) But here's my take on M82. 10x120s Lum, 10x180s R/G/B. 5x900s Ha. Alll bodged together in PI and photoshop. The Ha is really stretched, and it was taken with quite a lot of moon about (any excuse!) But you can see what it is at least. I know I should be doing better, but I'm busy renovating a house (with a nice dark garden - can't wait).
